Notes:

1. In cases where the common normal length values are not given in Tables 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, the measurement should be performed over rollers, since measuring the common normal length is unreliable due to the measuring surfaces being located near the radius of curvature or the edge of the tooth tip.

2. The values of the common normal length deviation coefficient given in Tables 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32 are equal to 0.866.

3. The calculation of limit deviations and inspection dimensions is given in Appendix 4.

5. Tolerances and fits

5.1. Tolerances and fits for centring on tooth side surfaces

5.1.1. The arrangement of the tolerance zones for the bushing space width e and the shaft tooth thickness s, as well as the designations of tolerances, fundamental deviations and limit deviations, shall conform to those shown in Fig. 5.

Fig. 5. Arrangement of the tolerance zone for the bushing space width e; arrangement of the tolerance zones for the shaft tooth thickness s

The limit deviations of the bushing space width and the shaft tooth thickness shall be measured from their common nominal size on the arc of the pitch circle.

5.1.2. Two types of tolerances are established for the bushing space width and the shaft tooth thickness:

Ts — tolerance of the actual bushing space width (shaft tooth thickness), checked separately in cases where a composite gauge is not used;

T — total tolerance, including the deviation of the actual space width (tooth thickness) and the form and position deviation of the elements of the space (tooth) profile, checked by a composite gauge.

5.1.3. The following accuracy grades of the connection elements, determining the values of Ts and T for the bushing and the shaft, are established, denoted by numbers:

bushing space width — 5, 6, 7, 9, 11;

shaft tooth thickness — 5, 6, 7, 8, 9, 10, 11.

The values of tolerances Ts and T are given in Table 1 of Appendix 2.

(Amended version, Amendment No. 2).

5.1.4. The following series of fundamental deviations are established, denoted by letters of the Latin alphabet (lowercase — for the shaft and uppercase — for the bushing):

for the bushing space width — H;

for the shaft tooth thickness — r, p, n, k, h, g, f, d, c, a.

The values of the fundamental deviations of the shaft tooth thickness are given in Table 2 of Appendix 2.

5.1.5. The designation of the tolerance zones for sizes e and s is established in the form of a number indicating the accuracy grade, followed by a letter indicating the fundamental deviation (to distinguish it from the designations adopted for plain connections, where the number follows the letter).

5.1.6. The tolerance zones for the bushing space width and the shaft tooth thickness shall conform to those given in Table 33.

Table 33

Accuracy grade	Sleeve	Shaft
	Fundamental deviation
	H	r	p	n	k	h	f	d	c	a
7	7H			7n		7h	7f
8			8p		8k		8f
9	9H	9r				9h		9d
10								10d
11	11H								11c	11a

Note. Tolerance zones underlined are preferred for clearance fits.

5.1.7. The limit deviations of size e for bushings shall conform to those given in Table 34, and of size s for shafts — in Table 35.

The same, for the internal splines of the joint:

50x2x9H GOST 6033-80

The same, for the external splines of the joint:

50x2x9g GOST 6033-80

b) for a spline joint with d=50 mm; m=2 mm, with centering on the outer diameter, with a fit on the centering diameter H7/g6, with a fit on the non-centering surfaces of the teeth 9H/9h:

50H7/g6x2x9H/9h GOST 6033-80

The same, for the internal splines of the joint:

50H7x2x9H GOST 6033-80

The same, for the external splines of the joint:

50g6x2x9h GOST 6033-80

c) for a spline joint with d=50 mm; m=2 mm, with centering on the inner diameter, with a fit H7/g6, with a fit on the non-centering side surfaces of the teeth 9H/9h — similarly, for the internal and external splines of the joint.

(Amended version, Amendment No. 2).

7. Inspection methods

7.1. The elements of spline joints are inspected with composite or single-element gauges for internal and external splines.

Figure 7 shows 3 methods of inspecting involute spline joints.

Figure 7. Methods of inspecting involute spline joints

The standard inspection method is carried out with a GO composite gauge and a NOT GO sector gauge (checking the total tolerance T).

Tolerance Ts is established as a reference value and is not used for accepting or rejecting parts.

7.2. Alternative Method A provides for inspection using GO composite gauges, NOT GO sector gauges, and composite gauges.

This method is used to ensure the maximum effective side clearance.

7.3. Alternative Method B is used where there is no need to check the deviation of form and position of the splines.

7.4. Spline joints are inspected with GO composite gauges and NOT GO single-element gauges.

Composite gauges must pass over the surface being inspected under their own weight. Inspection of a splined shaft or bushing with a composite gauge is sufficient in a single gauge position, without repositioning.

Inspection with a NOT GO single-element gauge must be carried out in at least three different positions. If the NOT GO single-element gauge passes in any of these positions, the part being inspected is considered defective. Instead of NOT GO single-element gauges, inspection of splined shafts and bushings using measuring rollers is permitted.

If the length of the composite gauge is less than 0.5 of the length of the surface being inspected, an additional check of the deviation from parallelism of the tooth sides of the product must be carried out. Recommended tolerance values are given in Appendix 2.

For inspecting splined shafts and bushings of the sixth and coarser accuracy grades, grade 3 gauges are intended; for inspecting the eighth and coarser accuracy grades, grade 4 gauges are intended.

Section 7. (Added additionally, Amendment No. 2).

Appendix 1 (informative). Selection of spline joint parameter values Hf and hf depending on the type of tool used

1. The nominal (basic) diameter of the involute spline joint d should, as a rule, be equal to the nominal bore diameter of the ball bearing.

2. The values of the bushing root circle diameter df and the shaft root circle diameter df1 are nominal when the tooth root height is Hf=hf=m.

3. When machined with a universal tool, the bushing root circle diameter increases relative to the nominal value by an amount equal to 0.2m, i.e. Hf=1.2m.

4. When machined with a universal tool, the shaft root circle diameter decreases relative to the nominal value by an amount equal to 0.1m (when machined with a hob) and by an amount equal to 0.2m (when machined with a gear shaper cutter). In this case, the shaft tooth root height is taken as hf=1.1m and hf=1.2m, respectively.

2. Calculation of limit deviations

2.1. Calculation of limit deviations for the bushing:

minimum size of bushing space width (go composite gauge) emin=d·π/2z+EI,

minimum size of bushing space width for element-by-element measurement emin1=d·π/2z+EI1, where EI1=EI+(T-Ts),

maximum size of bushing space width (no-go gauge) emax=d·π/2z+ES, where ES=EI+Ts.

2.2. Calculation of limit deviations for the shaft:

maximum size of shaft tooth thickness (go composite gauge) smax=d·π/2z+es,

maximum size of shaft tooth thickness for element-by-element measurement smax1=d·π/2z+es1, where es1=es-(T-Ts),

minimum size of shaft tooth thickness (no-go gauge) smin=d·π/2z+ei, where ei=es-Ts.

3. Calculation of inspection dimensions for element-by-element measurements

Since a spline joint cannot be manufactured without form deviations, the go limit is checked using composite gauges based on the Taylor principle.

The effect of form and position deviations is accounted for by the total tolerance T. For cases where composite gauges are not available, tolerances Ts (or the go limit dimension) are recommended for element-by-element measurement.

The values of tolerances Ts (or the position of the go limit) for element-by-element measurement depend on the manufacturing accuracy. The ratio T:Ts is taken as 1.6 and is recommended for medium manufacturing accuracy. It is advisable to determine the bushing space width and shaft tooth thickness from the inspection dimensions M and m. Measurement of the common normal length is unreliable due to the location of the measuring surfaces near the radius of curvature or the tip edge, so measurement over rollers should be preferred.

Limit deviations corresponding to the no-go and go limits of the measured quantity are calculated from the limit deviations of the space width and tooth thickness using the deviation coefficient ξ,

deviations for the common normal length are calculated using the coefficient ξW.

The limit deviations needed for gauge manufacture, corresponding to the go limit of the measured quantity, are calculated not using the deviation coefficient, but by formulas applied for gear transmissions.

4. Example of calculating limit deviations for element-by-element measurements

Using the calculation formulas given in Section 2, all limit deviations of the space width and tooth thickness can be determined for the specified accuracy grades and basic deviations.

An example of calculating limit deviations for element-by-element measurements of the spline joint 120x3x9H/8f is given in the table.
